Thermometric Sentence Examples

A Log Book is a marine or sea journal, containing, in the British navy, the speed, course, leeway, direction and force of the wind, state of the weather, and barometric and thermometric observations.

Its high coefficient of thermal expansion, coupled with its low freezing point, renders it a valuable thermometric fluid, especially when the temperatures to be measured are below - 39° C., for which the mercury thermometer cannot be used.

He remarks that ” the law according to which the motive power of heat varies at different points of the thermometric scale is intimately connected with that of the variations of the specific heats of gases at different temperatures - a law which experiment has not yet made known to us with sufficient exactness."

He experimented with an air-thermometer, in which the temperature was defined by measurement of the length of a column of mercury; and he pointed out that the extreme cold of such a thermometer would be that which reduced the "spring" of the air to nothing, thus being the first to recognize that the use of air as a thermometric substance led to the inference of the existence of a zero of temperature.

If Q is expressed in terms of this unit in equation (I), it is necessary to divide by c, or to replace k on the right-hand side by the ratio k/c. This ratio determines the rate of diffusion of temperature, and is called the thermometric conductivity or, more shortly, the diffusivity.

The methods of measurement, founded on rise of temperature, may be classed as thermometric methods, since they depend on the observation of change of temperature with a thermometer.

There Are Three Possible Kinds Of Unit, Depending On The Three Fundamental Methods Already Given: (I) The Thermometric Unit, Or The Thermal Capacity Of Unit Mass Of A Standard Substance Under Given Conditions Of Temperature And Pressure On The Scale Of A Standard Thermometer.

In Any Case It Is Necessary To Define A Thermometric Unit Of Class (1).

Which Is The Selection Of A Standard Temperature For The Water Thermometric Unit.

6° in January and 64° in July), and the extreme thermometric readings - 40° and 104° Fahr.

He carefully kept thermometric and meteorological statistics.; he imported silkworms and books on silk culture; he corresponded with many litteratinotably with Dr Nathaniel Lardner and with Sir William Jones, of whom he besought information of all kinds, but especially any that would lead to the discovery of the whereabouts of the ten lost tribes; and he undertook the study of Hebrew at the age of forty and became an able scholar.

The former investigates essentially general properties, such as the weight and density, the relation between pressure, volume and temperature (piezometric and thermometric properties), calorimetric properties, diffusion, viscosity, electrical and thermal conductivity, &c., and generally properties independent of composition.

Joule's views of the nature of heat strongly influenced Thomson's mind, with the result that in 1848 Thomson proposed his absolute scale of temperature, which is independent of the properties of any particular thermometric substance, and in 1851 he presented to the Royal Society of Edinburgh a paper on the dynamical theory of heat, which reconciled the work of N.
